SUMMARY:Positive state polynomials
CLASS:PUBLIC
DESCRIPTION:CS/MATH SEMINAR - IGOR KLEP\, UNIVERSITY OF LJUBLJANA\n\nThe ta
 lk will discuss state polynomials\, i.e.\, polynomials in\nnoncommuting va
 riables and formal states of their products. The\nmotivation behind this t
 heory arises from the study of correlations in\nquantum networks. We will 
 give a state analog of Artin's solution to\nHilbert's 17th problem showing
  that state polynomials\, positive over\nall matrices and matricial states
 \, are sums of squares with\ndenominators.
